What it means
The ratio is a straightforward measure of financial leverage, which is the extent to which a business relies on borrowed money rather than owners' money. Lenders and investors use it as a first read on how much cushion exists before creditors start to be at risk.
There is a definitional trap worth knowing about. Some analysts use total liabilities in the numerator, which includes trade payables, accruals and deferred income, while others use only interest-bearing debt such as loans, bonds and lease liabilities, and the two versions can differ dramatically for the same company.
What counts as a healthy level depends entirely on the industry. Utilities and property companies with steady, predictable cash flows comfortably carry ratios above 0.60, whereas a software business with volatile revenue and few tangible assets to pledge would look alarming at that level.
The ratio is a snapshot at a single date, so it can be flattered by timing. Drawing down a loan just after year-end, or paying down a revolving facility just before it, can move the reported figure without changing the underlying position at all.
Used properly, the number is a starting point rather than a verdict. Pair it with interest cover, which asks whether profits comfortably pay the interest, and with a look at when the debt actually falls due.
In practice
Real-world examples.
Example
A commercial landlord reports a ratio of 0.62 and its lenders are relaxed, because the buildings generate contracted rent and can be sold or refinanced. A staffing agency with the same 0.62 would face far harder questions, since its main asset is a book of receivables that shrinks the moment trading slows.
Example
A manufacturer's banking covenant caps the ratio at 0.55. When the finance team models a $2m equipment purchase funded entirely by loan, the projected ratio hits 0.58, so the board splits the funding between debt and retained cash to stay inside the limit.
Example
An investor comparing two retailers finds identical ratios of 0.45, but one has debt maturing in eighteen months and the other has it spread over seven years. The maturity profile, not the ratio, becomes the deciding factor.
Formula
Calculation
Total debt to total assets = Total debt / Total assets
A regional food producer reports total assets of $4,500,000. Its balance sheet shows a bank term loan of $900,000, a lease liability of $300,000, an overdraft of $150,000 and trade payables plus accruals of $450,000, giving total liabilities of $1,800,000.
On the broad definition, using all liabilities, the ratio is $1,800,000 / $4,500,000 = 0.40, or 40%. On the narrower interest-bearing definition, the debt is $900,000 + $300,000 + $150,000 = $1,350,000, though if the overdraft and lease are excluded as many lenders do, the loan-only figure of $1,200,000 gives $1,200,000 / $4,500,000 = 0.267, or 26.7%. Now suppose the producer borrows a further $600,000 in cash: debt rises to $2,400,000 and assets to $5,100,000, so the broad ratio becomes $2,400,000 / $5,100,000 = 0.471, or 47.1%.Case study
Seen in the real world.
Ashcroft Garden Centres is a fictional retail chain used here as an illustrative example. After three years of steady expansion funded by borrowing, its total debt to total assets ratio had drifted from 0.34 to 0.58 without anyone treating the trend as significant, because each individual store loan had looked affordable on its own.
The problem surfaced when the group approached its bank for a facility to fund a distribution hub. The bank's credit committee looked at the ratio alongside interest cover, which had fallen from 6.1 times to 2.3 times, and declined the request on the grounds that a single poor season would leave no headroom.
Ashcroft's response was to pause new sites for a year, sell and lease back two freehold properties, and use the proceeds to repay the most expensive borrowing. By the following year end the ratio had come back to 0.46 and interest cover to 3.8 times, and the same bank approved the hub. The finance director's takeaway was that the ratio needed to be reported to the board every month, not calculated once a year when the accounts were signed.
Watch out
Common mistakes.
- Comparing the ratio across industries without adjusting expectations. A figure that is conservative for a utility can be dangerous for a consultancy.
- Mixing definitions when comparing companies. Using total liabilities for one and interest-bearing debt for another produces a difference that reflects the method, not the businesses.
- Reading a low ratio as automatically good. Very little debt can mean an underused balance sheet and a higher cost of capital than necessary.
Questions
People also ask.
Is a lower ratio always safer?
Not always, because moderate debt is usually cheaper than equity, so an extremely low ratio may mean the company is leaving value on the table.
How does it relate to the debt-to-equity ratio?
They describe the same leverage from different angles; debt to assets compares borrowing with everything owned, while debt to equity compares it with owners' funds.
Do operating leases count?
Under current accounting rules most leases sit on the balance sheet as liabilities with matching right-of-use assets, so they affect both the numerator and the denominator.
